Check out this great post on what i think is the first great Diabetes care product for iPhone on the Diabetes Mine blog.
I have explored making an iPhone Glucose metering app several times. There are several significant challenges in such a project, and we never decided to go through with it. However, that did not make the need for such a product and app any less, and now i am finally relieved to see what i think is the first high quality iPhone diabetes product and app.
This product is made by Sanofi-Aventis. Based on their product marketing materials, please note that the actual app is not yet in the app store, the app design is excellent. It is very understated, simple and functional. The case design shows a clear understanding of mobility needs balanced against a patient's desire to not compromise their style or quality of life.
